This invention relates to battery handlamps,` and more particularly to that type of lamp in which a plurality of lighted selectively at thejwillof theoperator,

i Conventional flashlights are .provided `with 011B ormore4 Vbulbs as a source of light and `with one or more reflectors for causing the light tombe projected in `the form of more or less sharply light visible in darkness for a defined beams of n 4 long distance. Consequently,` Conventional flashlights may not` safely` be `used `under blackout conditions for illuminating lor signaling` purposes.-

The present invention provides a vflashlight hav-.-

one bulb mounted at thebottom ofa reector, for throwing a more or less sharply dened beam of lightfor use under `ordinary conditions; The flashlight of the present invention further in-` cludes a second bulb mounted Within thecasiner of the flashlight. Thelight from theseoond bulb. is admitted into thereflector in` a downward direction through `a hooded slot the reflector, whereby the lightfrorn the second bulb is projected from therellectorin anextremely diffused liorm so as not to be visible for a longdistance.

The reflector may be` formed ofia non-metallicmaterial,` for instancaa white plastic, to provide an evenly disused light; `The nashught of this bulbs are provided to" be` has its rear end in,

ninto a hooded, slotted .reflector insulating paneldisposed within the battery casing aboveltwo batteries disposed side by 'Side in the battery `casing lengthwise thereof. The bulb to be used` for normal illumination projects formed of' an insulatinglbone white plastic material. A metal strip attached tothe underside of the panel connects thecontact points of both bulbs to -the positivepole ofone of thebatteries,

a which are connected in series.

A longitudinal switch bar Permanent sliding contact with a negative ground. Upon forward move.` ment, the switch bar contacts abare wire'disposed on the outside :of the reflectorand `electrically connected to the bulb intended for normal illumi-` nation. On backward movement of the switch bar, the latter contacts a bare portion ofanother wire extending along the panel and electrically. connected to the bulb to be used under blackeout conditions. If desired, the aperture in the panel receiving the bulb intended for use under blackinvention is further provided with a sliding contact whichoperates to close a circuit energizing the bulb emitting the bright light when pushed one way, and to close a circuit energizing the secondbulb emitting dim light when pushed in the oppositedirection., i

More particularly, one type of flashlight accordingto this invention has `two bulb` sockets insulated from` each other, 4the socket for the bulb used for normal illumination being asleeve integral with a metallic` reector. The socket for `the bulb to bcused under black-out conditions is `formed `by a spring clip electrically connected to a spring bar extending across the interior of the flashlight casing past and spaced from the bulb socket `connected to the reflector and having a free end below the reflector. A longitudinal switch bar has its rear end in permanent sliding d contact with a negative ground. .Upon forward movement'ofVthe switch bar into contact with the reflector, Athe bulb intended for normal illumination is energized, 44.Upon backward movement o f fthe switch bar, `a projection on `the bar con-` tacts the free end of the spring bar to energize the bulb intendedto furnish faint light forvuse during black-outs. i. i i i In another form offlashlight according to the present invention, two `bulbs are `soclfetecln an out conditions `may have a smooth cylindrical in-` side, the wire `connecting the bulb electrically to itsenergizing circuit being disposed in the manner of a chord `within the aperture at the same angle as the pitch of thread in the bulb base whereby the bulb can be screwed into the aperture in spite of the absence of threads on the inside 0f the aperture. i

It is, therefore. an important object of the presentinvention to provide allashlight capablel of emitting a more or less sharply defined beam `of bright light for use during normal conditions, as well as a diffused dim or faint light for use under black-out conditions. l l

A further object of this invention is to provide a flashlight `having a` reflector formed with a hooded slot through which light may be admitted l from `a bulb disposed inside theashlight casing for projectionin dilused form from the reflector. A further objectof the invention is to provide a flashlight having a reflector formed of nonmetallic material `such as a white plastic` for projecting evenly diilusedlight therefrom.

Another` object of this invention is to provide` a ilashlight having a contact which, When moved i in one direction; closes a circuit including a bulb so disposed in `relation tolthe reflector as toV furnish abeam of bright light and,"whenrnov`ed in another direction, closes a second circuitins cluding a bulb sodisposed as to emit light which enters the reflector downwardly through a hooded slot to be projected in a diffused form. i i

As shown on the drawings:

In Figures 1 to 5, a ashlight according to this invention is indicated generally by the reference numeral I0 and includes'a casing II of flattened oval cross-sectional form and a cover I2. The casing and cover are both formed of insulating material, for instance, brous or resinous plastic materials. As shown in Figure 3, the casing II and the cover I2 are rabbeted at IIa and 12a so as to fit together in 4overlapping or' partly telescoping relationship. The outside of the casing IIVis formed with a series of parallel longitudinal ribs I3 intended for decorative purposes.

One side of the end of the cover I2 is pierced by a generallyoval aperture I rimmed by an internal flange IB. The .aperture I5 extends over more than half of the length of the cover end and is closed by a similarly shaped glass or lens I1 held against the underside of the rim AIt by a refiector I8 shaped similarly to the aperture I5 and force-fitted between the side wall of the cover and a dependent flange I9. extending from the cover sidewall around the aperture I5. -The reflector I8 is provided with an extended sleeve 2D for holding a light bulb 2l. The sleeve or socket 2U is formed with depressed spots or dimples 20a staggered to engage the threads of the bulb 2l. The sleeve or socket can also be formed to provide a snug t therein of the bulb- 2l and may have formed therein a small depressed spring which will engage the threadfof the` bulb with spring pressure for securely holding the bulb.

The casing I I is formed with a short internal rib or stem 23 extending from one short side wall below the aperture I5 toward the other short side wall to provide lateral support for two batteries or dry cells 24 and 25, whose ends do not occupy anywhere near the entire bottom surface of the casing. As shown, the battery 24 further away from the stem 23 has its positive pole turned up, while the battery 25 adjacent the stem 23 has its positive pole turned downward. A connecting spring 26 connects the two batteries electrically while at the same time lifting the two batteries off 4the inner bottom surface' of the battery case, the battery 24 being lifted somewhat higher than the battery 25. The clip 26 further serves to Icushion any shock to which the batteries 24 and 25 `may be subjected should the flashlight be handled roughly or dropped.

As shown in Figure 3, the battery 24 extends highervthan the" battery 25. Disposed on top of the battery 25, and held against lateral displacement by the battery 24 and longitudinal ribs 21 on the inside of the casing II, is a connecting assembly 29, including a generally square flat insulating member 30 of rubber` or other insulating material and a lower flat insulating member v3| extending laterally beyond the covering member 30. As shown in Figure 5, the 4members 30 and 3l are formed with 'bevelled corners. andthe member 3I has edge recesses 3Ia, for receiving the ribs 21. Over the top ofthe` member 30 extends a contact bar 32 having an offset end projecting laterally so as `to overlie the positive pole member of the battery 24. The members 30 and 3| and the contact bar 32 are held in 4assembled relationship by a rivet member 33 whose lower head is countersunk into the member 3| so as not to contact the negativel pole of the battery 25.`

A second contact bar `34 is clamped between the members 3I and 30, in spaced relationship to the contact bar 32, and projects laterally awayfrom the battery 25 to present a downwardly deflected end portion extending in `closely spaced relationship to the end'wall whence projects the stem 23.

This contact bar 34is connected electrically to `the negative pole of the battery 25' by asecond rivet 35 piercing the member 3| and the conta-ct bar 34 and having one end projecting from the.l underside of the member 3| into contact with the negative pole of the battery 25. 'I'he under side of the member 30 isformed `to provide a recess to accommodate the other head of the rivet 35. y

As shown in Figure 3, the contact point of the bulb 2I contacts Athat part of the contact bar.

32 above the member 30. The contact point of a second electric bulb 31 contacts the off-set end of the contact bar overlying I thepositive pole of the battery 24. The bulb- 31 isheld .in place by an appropriately shaped spring `clip 38. This spring clip may be shaped, for instance,4

in the form of a U having 'the legs thereof expanded to accommodate the bulb. The expanded.

portion is suitably formed with staggered dimples or depressed spots 38a adapted to engage the threads of the bulb. vThe clip 38 may be held in place by having a slightly expanded bottom part inserted into a groove 39 formed in a slightly thickened side wall section 40. As shown` in Figure 5. a cross bar 42 having an end bent back upon itself and held between the spring clip` 33 and the casing wall extends across one long side of the casing supported bythe top of the ribs 21 in spaced relationship to the socket 20 with its curved free end extending around the short casingwall whence projects'the stem 23 in fairly close or yspaced relationship `to the latter side wall.

Above the stem 23 the top of the casing side wall is pierced by a longitudinal slot-44, and

the overlapping portion of the cover I2 is piercedtached tothe topo-fthe casing,

y 2,383,223 by a registeringslot 45. u A switch member-46` shorter than thetwoslots 44 and 45 is movable therein, being provided with an outer knurled knob 46a `having terminalv projections tlfiatwslidefv upon the outer short `casing side wall beyond the upper `and lowerends ofthe slotsj44` and` 45. yAttachedtorthe inside ofthe switch memi ber 46by means I of a `screw 41 is `an elongate contact` bar 48 having' an inwardly `offsetend 48a which slides over the deflected end of the` contactmember 34 in permanent contacttherewith. Aeroeve su formed in the side wen of! As `shown in Figures V3 and 4, the `reiiector I8 `is pierced by `a transverse slot Bladjacent thebulb 31, and the wall of the relectoris` bent inwardly above the slot 54 to forma hood 55 which will directlightfrom the bulb 31 admitted through the slot, 54 downwardly into the reecton, j i

jecting from ;the bottom of the lcasing lifts the battery ,1d above the `level. to whichthebattery 1-5;is liftedvfby a coiled spring 18 disposed between `transverse ribs-,19 4rising from the bottom of the casing. `A wire 8l)` connects the two coil` springs 1li-and 18, electrically, and thereby also the ltwo batteries Hand.; 15. As shown Figs.. 7 .and 8, theybattery 14fextends `higher than Athe battery 1:5. A pane-1 8.1?, .formed of .insulatingmaterial extends acrosst the casing ill having one end spaced by substantial distance from the casing side xwhenceeprojects the c. stem 13 andanother 'end' closely 'spaced from the opposite casing side.

Above Ithetbattery 15 the panel 83 is pierced by a round internally threaded aperture 84 receiving in threaded engagement the threaded base of a bu1b-85 intended for illumination under normal conditions and having an enlarged base portion received within the depending flange as well as a bulb portionl extending into the reector 68. Above the battery 14 the panel 83 is pierced by a round aperture 86 which is not threaded internally and which receives the threaded base portion of a bulb 81 intended for illumination under black-out conditions. A rib 88 projects inwardly from the coverftop opposite the end of the bulb 31 for limiting any upward movement of vthis bulb. Adjacent the bulby 81, the reflector is slotted at 89 and provided with a hood 90 for reflecting light emitted from the bulb 81 downwardly-into the reflector' |58.v

Between the apertures 84 and 86 a metal strip 92 is affixed to the underside of the panel 83 by means of a rivet or screw 93. The strip 92 is offset below the bulb 81 so as to provide an electrical connection between the .contact point of the bulbv 81' and the positive pole of the battery 14. This offset portion of the strip v92 has an upwardly deflected end portion which occupies the 'space between the corresponding end portion of the panel83 and the inside of the cap 82, the tip 'of the strip 92 being further deflected inwardly to lielon the top end surface of the panel 83. The other end portion of the strip 92 is offset to contact the contact point of the bulb 85, the

' tip ofthis end portion of the strip being deflected downwardly. Enfolded by the offset end portion of the strip 92 underlying the contact point of the bulb 85 is' an insulating member 94 whose outside abuts against the downwardly deflected tip of-this-end portion of the strip 92. A metal strip 95 is affixed to :the underside of the insulating member 94 by means of a rivet 98 having a lower'h'ead contacting the negative pole of the battery and an upper head countersunk within the body 94 so as not to contact the strip 92. The inside end of the strip 95` is deiiected upwardly so asjto be folded about the lower inside edge of the insulating ymember 94. On the out.- side, the member 95 is offset upwardly, and the o'ifset' portion is affixed to the outside end pory `tion of the panel 83 by means of a. rivet 91. Beyond the rivet 91 the strip 95 is curved downwardly and terminates in ajstraightportion 95a urgedby the spring'action of the downwardly curved portion against the inside of the casing 8| lengthwise-thereof. The middle of the straight portion 95a is curved'inwardly, for a purpose to be disclosed hereinbeloW.

A bare metal wire |00 extends across the free end`ofthe panel 83 adjacently and parallelwith the top edge thereof. One end of this wire is deected inwardly and buried in the end of the panel 83. On the other side of the end of the panel 83 the wire |00 is bent about a screw |0I.

extending into the end surface of the panel 83,

, the lwire |00 then extending downwardly along the outer edge of the end of the panel 83. The wire |00y the-n extends along the bottom surface of thepanel 83 within insulating material |02 as far as the rivet 93. As shown in Figures 9, l0 and 12, the wire |00 then extends diagonally across the panel 83 at an upward angle equal tothe pitch of the thread in the base of the bulb 81 within a groove |03 formed in the bottom of the panel 83. As illustrated in Figure'12, the vwire |00 is laid at the bottom of the relatively deep groove |03 and held in the groove by staking, the material forming the walls of the groove 4being peened down n.

over the Wire. As shown in Figures 9 and l0, the diagonaldirection of the'groove `|03 is such that the groove enters thel aperture `Sli through the panel 83, a portion ofthe side wall'Y of the groove being absent and thewire |00 projecting into the aperture 86, whereby aA wire portion |04 projects into the aperture which wire portion |04 can be used for threading vthe bulb 81 into the aperture 86. The Wire |00 terminates past the wire portion |04 flush with `the surface of the panel 83. v

Above the stem 13 the top of the casing side wall is pierced by a longitudinal slot |06, and the overlapping portion of the cover 62 is pierced by a registering slot |01.` A switch vmember |08 shorter than the twosmts sus and loris movabie therein, being provided with an outer knurled knob |08a having terminal projections that slide upon the outer short casing wall beyond the upper and lower ends ofthe slots |06 and |01. Attached to the inside of the switch member I|08 by means of a screw or rivet |09 is an elongated contact bar ||0`capable of sliding lengthwise of the casing within a longitudinal groove formed in the casing wall. The` lower endl portion of the contact bar ||0 is slotted longitudi-f nally at I |2 and this slot is pierced by a screw I I3 projecting inwardly from the casing wall and serving as a stop for upward andy downward movement of the contact bar ||0. Shortly above the slot |I2 the contact bar is formed vwith an inwardly curved portion I |0a adapted to mate with the inwardly curved portion of the end portion 95a of the negative ground strip 95,` when the Iswitch is in neutral position. The upper end of the contact bar ||0 is bent inwardly and terminates with an outwardly bent tip. The curved bar end is adapted to contact'the bare wire |00 laid across the end of the panel 83 when the switchmember is moved downward, and the outwardly curved tip of the Contact bar end is adapted to contact the bare wire 1| `extending downwardly along the outside of the reflector 68 when the switch member is moved upwardly. l

When the bulb 85 is to be energized forillumination purposes under normal conditions, the knob |08 ispushed forward. The then closed circuit includes the bulb 85, the wire 1|, the Contact bary I I0, the negative ground strip 95, the batteries 15 and 14, and the contact strip 92`.Y vWhenthe bulb 81 is to be energized for illumination or signaling purposes under black-out conditions, the switch knob |0811 is pushed? back. vThe circuit then closed includes the bulb 81, the wire I 00, the

contact bar ||0, the negative ground strip 95, vthe' batteries 15 and 14, andthe contact strip 92. If

neither bulb is to be energized, the knob' |0'8a is disposed so that the inwardly curved portion I |0a of the contact bar ||0 nts within the mating inwardly curved portion of the negative ground strip and so that the inwardly curved top end portion of the contact bar |,I0 contacts neither the aesaeas connected assemblyincluding `the panel 83 and theinsulating member 94 is inserted, thebulbs 85 and l81 'are screwed into the apertures 84 `and 86,
